Makina oziziritsa ozizira amatengera ma disc ndi zida zowongoka ndipo AMAGWIRITSA NTCHITO mfundo yosokoneza yachiwiri kuti apange mitu yosiyanasiyana, mutu wowuma, mutu wa semi-countersunk, socket ya hexagon ndi ma bolts ena omwe sali wamba komanso zida zamakina.
Nanga ndi zofunika ziti za makina ozizira mutu kwa zipangizo zake processing?
1.Kupanga mankhwala ndi makina azinthu zopangira mutu wozizira wa makina ozizira a pier ayenera kukwaniritsa miyezo yoyenera.
2.Wopanga makina ambiri ozizira mutu wozizira adafotokoza kuti zinthuzo zidathandizidwa ndi spheroidization annealing, ndipo mawonekedwe a metallographic a zinthuzo anali ozungulira pearlite giredi 4-6.
3.kuuma kwa zopangira, kuti muchepetse chizolowezi chophwanyidwa chazinthu momwe mungathere, kuwongolera moyo wautumiki wa nkhungu kumafunikanso kuti zinthu zozizira zojambulidwa zimakhala ndi kuuma kotsika kwambiri momwe mungathere, kuti apititse patsogolo plasticity.Kulimba kwa zipangizo nthawi zambiri kumafunika kukhala pakati pa HB110 ndi 170(HRB62-88).
Kujambula kwa 4.cold kwa inchi yolondola yokwanira iyenera kukhazikitsidwa pa zofunikira zenizeni za mankhwala ndi ndondomeko ya ndondomekoyi, makamaka, pofuna kuchepetsa m'mimba mwake ndi kukula kwa zofunikira zenizeni za zochepa zochepa.
5.Wopanga makina othamanga kwambiri ozizira amafotokoza kuti mawonekedwe a pamwamba pa zinthu zoziziritsa kuzizira amafuna kuti filimu yopaka mafuta ikhale yakuda komanso yonyezimira, ndipo pamwamba pake sayenera kulembedwa ndi zikopa, mapindikidwe, ming'alu, dzimbiri, mamba, maenje, kuvulala ndi zovuta zina.
6.The makulidwe okwana a decarburization wosanjikiza mu utali wozungulira wa zinthu ozizira kujambula si upambana 1-1.5% ya awiri a zopangira (zochitika zenizeni zimadalira zofuna za wopanga aliyense).
7.kuonetsetsa kuti mawonekedwe ozizira apangidwe amadulidwa, zojambula zozizira zimafunika kuti zikhale zolimba, koma mtima ndi wofewa.
8. ozizira zojambula zakuthupi ayenera kuchitidwa ozizira yopuma yopuma mayeso, pa nthawi yomweyo, zinthu sayenera tcheru kuzizira kuumitsa, pofuna kuchepetsa mapindikidwe ndondomeko, chifukwa kuzizira kuuma mapindikira kukana chinawonjezeka.
